Achieving granular file permissions with ACLs

If you need to add permissions to files or folders beyond User, Group or Other, then ACLs are the answer.  You can have super fine control over files and folders with ACLs and assign them based upon any number of users and groups.  Erin Scott over at the 318 has you covered on how to use ACLs.  This article outlines how to apply ACLs as well as the various permission types you can set.  It is a great read for those new to ACLs as well as those who have used them in the past.  Check out the article here.
